vLetters Patent No. 99,363, dated February 1, 1870.

IMPROVEMENT IN WIND-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same To all whom tt may concern Be it known that I, E. S. SMITH, of Macomb, in the county of McDonough, and State of Illinois, have invented a new and useful Improvement in Vindmills; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of refence marked thereon.

This invention relates to that class of windmills in which the fans are automatically adjusted by the action of the wind; and consists, rst, in the peculiar' construct-ion of the fan-shafts, and in the manner of attaching the fans or sails to them second, in the manner of connecting the mill to its standard;v and, third,

' in the employment of a float, in connection with a cord and brake, for the purpose of regulating the supply of water delivered by the pump.

It further consists, also, in certain details of construction, which, in connection with the foregoing, will be fully described hereinafter.

In the drawings- Figure l representsa side elevation of my improved mill,

Figure 2, a central vertical section of the standard, and

Figure 3, a detached view of lone of the fans.

To enable others skilled in the art to make and use my invention, I will now proceed to describe fully its 'operation and construction.

A represents the standard upon which the mill rests, which consists simply of a round rod or ple, of suitable size and sti`iiess,'which is firmly secured to a proper base.

` B represents a box or case, which rests upon the standard A, as sh'own, and revolves freely therein, in either direction. Upon this box all the machinery of the mill is built.

b b represent the side-pieces of the box, which, extending above the` end-pieces, as shown, form supports for the guiding fan-shaft C. Between .these supports are also located the brake d and eccentric lever d.

The brake ll is provided with a fulcrum, d2, and has, also, one ofits ends much heavier than the other. By means of this arrangement, the brake, when in its natural posit-ion, is inoperative.

The eccentric leverd1 is pivoted, as shown, between the upper ends of the irons E, and is operated by a cord attached to its ti'ee end,which passes through thek brake and top of the box, down into the well, and is attached to a float.

F represents the crank-shaft, which turns in bearings upon the projections b 11..

To one end of this shaft is attached the upper end of the connecting-rod G, the lower end of which latter' is attached to the swinging U-shaped iron H.

To the other end of the crank-shaft is attached a head, I, consisting ot' two crossed beams, as shown.

Upon this shaft is also placed the wheel J, which revolves just beneath the working end ofthe brake d, as shown.

To the ends of the beams constituting the head I, are attached the inner ends of the fan-shafts K. Each of these shafts consists of a at metallic bar, which is twisted near its base, as shown in fig. 3, so that its straight lengths are about at right an gles to each other.

These shafts terminate in round rods, as shown.

L L represent the fans or sails, which are constructed of any suitable material, and provided with the crossbars l Z. By means of these bars, the fans are secured to the shafts, as shown, a wide connection being used at the inner ends, to correspond with the form of the flat bar,and a simple staple at their outer ends, for the purpose of enclosing the rod.

M M represent springs, by means of which the'fans are ordinarily held to their places.

N represents the pump-box, which has a vertical re volving movement upon the standard A. Itis attached to the swinging iron H, by means of a connecting-rod, as shown.

The iron H, it will be obscrved,is provided with 0riices at different points, in order that a longer or shorter play of the pump-box may be obtained at will. The lower part of the pump-box is provided with a wrist, a, in which is located a' sleeve, n', as shown. By this means the former is enabled to revolve freely in the4 latter'.

To the sleeve n is attached the pump-rod O.

The operation of my windmill is as follows:

The mill, running in the usual manner, operates, through the various connections described, thepumprod, and thus causes the delivery4 of the water to the tank or trough, in the usual manner.

IVhen suiiicient water has been pumped from the well to furnish the desired sup'ply, its surface will be so lowered as to cause thc ioat to hang down, and becomea weight, and thuspress the brake upon the wheel,'and stop the mill. The brake, of course, may be 4perfectly adjusted to stop the lmill when any desired quantity has been pumped, by simply shortening lor lengthen-l ing the rope.

The fans are automatically adjusted as follows: \Vlien the wind is blowing lightly, the fans remain in the usual position, well exposed to the wind, being thus held by their springs, as shown; but if a heavy wind arises, the force of the springs is overcome, and

it a. strong and cheap mill, especially for pumping-purposes, cztn be produced.

Having thus fully described my invention,

That I cla-im as new, and desire to secure by Letters Patent, is

1 The combination of a. fztn-shztft, formed oi' :t twisted bnr, with n fan, when the lutter is free to move upon the former, as described, for the purpose set forth.

2. The combination of the box B, supportpg,r the mill, with the standard A, in the manner described, for the purpose set forth. v

3. The employment of zt float, in connection with :t brake, d1, and wheel J, in the manner described, for the pulpose set forth.

,4. The combination of the fans L, fen-shafts K, and springs M, in the manner described, for the purpose set forth.

5. The combination of the eccentric lever d1, weighted brake cl, wheel J, cord, and oat, in the manner described, for the purpose set forth.

(j. The pumping-box N, with wrist n and sleeve n', when operated its described, for the purpose set forth.

7 The Windmill described, consisting, essentially, of the standard-box B, guidingan, crank-shaft F, head I, wheel J, fen-shafts K, fans L, and pumping-box N, with the connections, when constructed land arranged as described, for the purpose set forth.

rlhis specification signed and witnessed, this 28th dzty of October, 1869.
